Is Yahoo CEO Marissa Mayer eyeballing Tumblr?

Early Thursday morning reports began to surface about rumors of Yahoo preparing a bid for social blogging site Tumblr. This would put the once king of search on the front lines of the social media war.

AllThingsD reported on Thursday that Yahoo was considering the acquisition of Tumblr for $1 billion. This is not the first time CEO Marissa Mayer has shown interest in Tumblr though. As an executive at Google, Mayer closely watched the blogging service loved by hipsters all over.

The rumors carry some weight as AllThingsD is usually spot on with its predictions on all things Yahoo, and there have been documented meetings between Mayer and Tumblr top execs including founder and CEO David Karp. While the acquisition seems imminent, we are left wondering what will happen to all of the Tumblr pr0n if Yahoo does take over.
